I'm working on some graph generation problem where the node identity
is significant (e.g. "if node1 is node2: # do something) but ideally I
wouldn't want to impose any constraint on what a node is (i.e. require
a base Node class). It's not a show stopper, but it would be
problematic if something broke when nodes happen to be (small)
integers or strings.
